2 Claims.

This invention relates to a coupling. An object of the invention is to provide a coupling of the character described specially designed for connecting sections of pipe, or the like, and' the invention has particular relation to certain novel features of construction, arrangement of parts and use, an example of which is given in this specification and illustrated in the accompanying drawing, wherein:

Figure 1. shows a longitudinal sectional view of .the coupling.

Figure 2 shows a transverse sectional view taken on the line 2-2 of Figure 1.

Figure 3 shows an end view of a modified form thereof.

Figure 4 shows a-longitudinal sectional view of said modified form.

Figure 5 shows an end view of still another modification, and

Figure 6 shows a longitudinal sectional view of the form shown in Figure 5.

In the drawing the numerals 1 and 2 designate confronting coupling members which are internally threaded to receive the ends of the connected pipe sections 3 and 4. The coupling member 2 has an external annular fiange 5 at its inner end provided with the marginal notch 6 and the coupling member l has the external fiared 40 shoulder 7 at its inner end. The facing ends of the couplings 1 and 2 have the opposing annular grooves 8, 9 in which is seated the seal ring 10 which forms a fluid tight joint between said coupling members.

Around the coupling member 1 there is an annular clamp fiange 11, which at' one side, has the dependingclamp 12 adapted to engage underneath the fiange 5 when the parts are assembled, and opposite this clamp there is a clamp bolt 13 whose upper end is fitted into a notch 14 of the fiange' 11 and pinned therein by the pivot pin 15. In the form shown in Figures l and 2,' the clamp ring 11 has a marginal notch 16 and in this form in assembling the parts the clamp 12 may be passed through the notch 16 and the ring With the above and other objects in view,`

11 then turned to engage the clamp 12 underneath the fiange 5 and to .align the notches 6, 14. The bolt 13 may be then swung into the notch 6 and a nut 17 screwed on to the free end of the bolt 13 and tightened up to clamp the parts 5 in assembled relation.

In the form shown in Figures 1 and 2 the clamp ring 11 fits closely over the coupling member 1 but in the form shown in Figure 4 the clamp ring 11 is fitted loosely on the coupling member 1. Acoordingly in the form shown in Figures 3 and 4 the marginal notch 16 is not necessary. for the reason that the ring 11 will have sufiicient lateral play relative to the coupling member 1 to permit the parts to be assembled as shown in Figure 4 and the bolt 13 may then be swung into the notch 6 and the nut 1'? tightened up as above explained.

In the form shown in Figures 5 and 6 the coupling 1 is similar to that shown in Figure 1` 20 and the coupling 2' has an external annular fiange 5' at its inner end provided with a plurality of .marginal notches 6'. Fitted around the coupling 1 there is the annular clamp ring 11' having the marginal notches 14' aligned with the notches 6'. In this form the bolts 13' each have one end pivoted in the corresponding notch 14' by a pivot pin 15 and the other ends of these bolts may be swung into the corresponding notches 6' .and the nuts 17 then tightened up to clamp the assembled parts together. In other' respects the form shown in Figures 5 and 6, is the same as' that shown in Figure 1.

The drawing and description disclose what are now considered to be preferred forms of the invention by way of illustration only while the broad principle of the invention will .be defined by the appended claims.

What we claim is: v

1. A coupling comprising two coupling members having facing annular grooves, a seal ring in said grooves, one coupling member having an annular fiange, an external shoulder on the other coupling member, a clamp ring on said shoulder around the corresponding member, said ring and fiange being provided, one with a marginal'notch and the other with a pivotally mounted bolt received by said notch, a clamp nut threaded on the free end of thebolt and abutting the adjacent, notched part, a marginal clamp on said ring, said fiange having a marginal notch to permit the passage of ,the clamp therethrough whereby the ring may be turned to engage the clamp with the outer side of the fiange.

2. A coupling comprising two coupling memcent notched part, a marginal clamp on the ring,.

said fiange having a marginal notch to permit the passage of the clamp therethrough whereby the ring may be turned to carry the clamp into engagement with the flange.
